RecognitionData partitioning using independent components analysisStephen

چکیده
Problems in data analysis often require the unsupervised partitioning of a data set into clusters. Many methods exist for such partitioning but most have the weakness of being model-based (most assuming hyper-ellipsoidal clusters) or computationally infeasible in anything more than a 3-dimensional data space. We reconsider the notion of cluster analysis in information-theoretic terms and show that independent component methods may be used to estimate the number and structure of probable data generators.

متن کاملStudy on the variation of plant species diversity components along elevation gradient using additive partitioning (case study: protected area of Geno, Hormozgan province)
Conservation of vegetation is one of most important tools for conservation of soil and decreasing erosion. Therefore, knowledge about vegetation characteristics, such as diversity, is the first and most important biological tools for soil conservation. One of the methods in which we can collect useful data about plant diversity, is additive partitioning. In the current study, plant species dive...

متن کاملCovariance among independent variables determines the overfitting and underfitting problems in variation partitioning methods: with a special focus on the mixed co-variation
The effectiveness and validity of applying variation partitioning methods in community ecology has been questioned. Here, using mathematical deduction and numerical simulation, we made an attempt to uncover the underlying mechanisms determining the effectiveness of variation partitioning techniques. The covariance among independent variables determines the under-fitting and over-fitting problem...
